Solution

The correct option is D Statement-I is true, Statement-II is true ; Statement-II is correct explanation for Statement-I.
As the vectors are non-equal so two vector can not make zero resultant.
According to triangle law of vector addition at least 3 vectors are needed to make zero resultant.
Thus, we can say that statement -2 is the reason of statement -1.
